Tip & How-To about Chevrolet S 10
When installing an new intake manifold gasket it is necessary to carefully align the manifold while setting it. This is due to the fact that silicone is used on each end and it is important to not move the manifold when setting it. To assist in a perfect setting, go to a hardware store and purchase a couple or more bolts of the same thread pitch as the manifold bolts. Cut the hex heads off the bolts and hand screw the headless bolts into several places in the block. Make sure the bolts are long enough to be useful and easily removed when the manifold is set. Set the manifold straight down. Set a few factory bolts and then remove the threaded pins used to align. Best to use new factory bolts when replacing a manifold. Finish by setting all bolts and torquing in correct pattern to correct torque.

Unscrew the bolt that holds the negative connection to the Impala's
battery. Set this bolt aside for later use.
Remove the engine cover to access the intake manifold and manifold
gasket. Disconnect the throttle body inlet duct from the engine.
Twist off the radiator cap to allow draining of the coolant to flow more
smoothly. Place an empty container beneath the radiator's drain plug, and
remove this plug. Allow all of the engine coolant to drain into the empty
container. Replace the drain plug once you are finished.
Tag all of the electrical wiring and hoses before removing so that
reconnection is precise to factory settings. Remove these parts, individually,
from the intake manifold.
Loosen the bolts that hold the intake manifold to the Impala's engine
block. Lift the intake manifold from the block once all bolts have been
Use the flat-head screwdriver to pry the old intake manifold gasket from
the engine block. Discard this part once you have removed it.
Clean the engine block thoroughly with the engine degreaser and linen
cloth. If necessary, use a gasket scraper to remove excess buildup and grime.
Place the old intake manifold on top of the newly-installed manifold
gasket until it aligns with all of the holes of the cylinder flanges and
Attach all of the bolts with your hand to the manifold. Once all bolts
have been positioned, use a torque wrench and apply 15 foot-pounds of pressure
to the bolts to secure the manifold into place.
Reconnect all of the necessary hoses and electrical wiring to the
intake. Pour the engine coolant back into the radiator.
Reattach the engine cover on top of the intake manifold and engine
block. Start the Impala's engine and check for any leaks around the new intake
